About Celsius Heat Unit per hour per square foot
The Celsius heat unit per hour per square foot (CHU/(h·ft²)) equals (9/5)×1055.05585262/(3600×0.09290304) ≈ 5.6783 W/m². The CHU (= 9/5 BTU(IT)) uses a 1 °C temperature interval instead of 1 °F; historically used in UK and Canadian heating engineering. 1 CHU/(h·ft²) ≈ 5.6783 W/m² = (9/5) × BTU(IT)/(h·ft²).
About International table kilocalorie per hour per square metre
The international table kilocalorie per hour per square metre (kcal(IT)/(h·m²)) equals 4186.8/3600 ≈ 1.1633 W/m² (1 kcal(IT) = 4186.8 J; 1 h = 3600 s). The IT variant used in steam engineering, solar thermal collector standards, and process heat calculations. 1 kcal(IT)/(h·m²) ≈ 1.1633 W/m².
